Unfortunately, today is already tomorrow for you. However, if it were still today, I thought this would be good reading for a day devoted to bikes:
It touches on subjects of interest: stupid motorists, bike lanes, mountain bikes, etc.
BTW, what I observe at the trail head is that mtn bikers often prefer to discuss mountain biking more than actually doing. They need a lot of rest time to discuss the gnarly line they took through obstacle such and such. Lots of waving hands around like leaning bikes swishing through obstacles required. And then "ride" over, it is time for lunch... or beers... depending on the time of day. Then home to observe the strava recorded heart rate during the epic dropper post debate earlier in the day.
